you are quite a strong demon slayer because you are a onerank lower than hashira

you were on a mission to kill 5th lower moon and a few side demons

you just killed one of the spider demons, you already hid your weapon but you heard a voice from the tree

"I saw your struggle, you must become a demon and join my family" said the demon

frowned "why would I join your family? I'm a demon slayer, I won't become a demon because you want me to"
